  • Patent number: 6074764
    Abstract: The cladding material 10 comprises a metal substrate 1, an expanded metal mesh 3 placed on the metal substrate 1 and a corrosion resistant metal lining 4 is placed in contact with the metal mesh 3 in opposition to the metal substrate 1 with the metal mesh 3 inbetween. A metal mesh layer placed on said metal substrate 1 may comprise an expanded metal whose openings are formed by making staggered cuts in a metal plate over the whole part thereof so that each cut passes through the thickness of said metal plate, and expanding said metal plate in a direction intersecting the length of said cuts thereby opening each cut.

  • Patent number: 5874178
    Abstract: The cladding material 10 comprises an Fe-based metal substrate 1 consisting of Fe or an Fe-alloy, a Ni-based metal layer 2 placed on the Fe-based metal substrate 1 and a metal mesh 3 placed on the Ni-based metal layer 2 in opposition to the Fe-based metal substrate 1 with the Ni-based metal layer 2 inbetween. Furthermore, a corrosion resistant metal lining 4 is placed in contact with the metal mesh 3 in opposition to the Ni-based metal layer 2 with the metal mesh 3 inbetween. The Fe-based metal substrate 1, the Ni-based metal layer 2, the metal mesh 3 and the metal lining 4 are bonded together by seam welded portion 8, which is provided in a planer or a linear form by using roller electrodes 6. The metal lining 4 consists of a metal whose main component is the one selected from Ti, Zr, Nb, Ta and Ni, or consisting of a stainless steel.
